''Parcoblatta fulvescens'', the fulvous wood cockroach, is a species of cockroach endemic to the United States and possibly Canada that measures around long.〔〔〔 ==Description== The male ''Parcoblatta fulvescens'' is relatively slender, has long tegmina (outer forewings), and is slightly longer than the female.〔 It is a mostly uniform pale brownish-yellow, with sometimes darker pronotum (the plate behind the head) and legs, and usually dark brown cerci (the pair of appendages on its rear-most segment).〔 Its pronotum is subelliptical (nearly elliptical), is widest just behind its middle, and has weakly defined disc-like impressions.〔 The female head and pronotum are usually a pale reddish-brown, its short tegmina are reddish brown with paler sides, its abdominal segments are a darker brown, and its legs and underside are a brownish yellow.〔 The species' ootheca (egg case) is bean-shaped, very dark brown, and measures about long by wide.〔 The edge with a seam is curved and has about 40 small crimps or folds.〔 It is similar to the ootheca of ''P. virginica'', but is larger and has slightly narrower spacing of vertical divisions.〔 Two differently colored forms of the species were regularly collected in Kansas: a dark, olive gray to brown variety from Riley County, Kansas, and a light, golden brown to tan variety from the slopes of the Flint Hills pastures near Manhattan, Kansas.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parcoblatta fulvescens」の詳細全文を読む スポンサード リンク
